Dollhouse for a dollhouse scale for 1:12 dollhouses. Commonly used for mini armor. Used for 12 mm, and 12.5 mm figure scale miniature wargaming. 1:128: 3 ⁄ 32 in: 2.381 mm A few rockets and some fit-in-the-box aircraft are made to this size. 1:120: 0.1 in: 2.54 mm: Model railways (TT) Derived from the scale of 1 inch equals 10 feet.TT model ...
For example, aligning the rightmost 1 on the C scale with 2 on the LL2 scale, 3 on the C scale lines up with 8 on the LL3 scale. To extract a cube root using a slide rule with only C/D and A/B scales, align 1 on the B cursor with the base number on the A scale (taking care as always to distinguish between the lower and upper halves of the A scale).
Following the patent and release of Harold's Long Scale calculator featuring two knobs on the outside rim in 1914, he designed the Magnum Long Scale calculator in 1927. [6] [7] As the name "Magnum" implies, it was a fairly large device at 4.5 inches in diameter—about 1.5 inches more than Fowler's average non-Magnum-series calculators. [8]
A slide rule consists of a body [note 1] and a slider that can be slid along within the body and both of these have numerical scales inscribed on them. On duplex rules the body and/or the slider have scales on the back as well as the front. [2] The slider's scales may be visible from the back or the slider may need to be slid right out and ...
Model railway scales and gauges are standardized in NEM 010, [1] which covers several gauges for each scale. Narrow gauges are indicated by an additional letter added after the base scale as follows: no letter = standard gauge (1,250–1,700 mm or 49.2–66.9 in) m = metre gauge (850–1,250 mm or 33.5–49.2 in) e = narrow gauge (650–850 mm ...
The dominant scale used in the United States for models of "standard gauge" trains running on 45 mm (1.772 in) track, even though 1:32 is more prototypically correct. 1:29 represents standard gauge using 2 in (50.8 mm) gauge track, the original gauge 2. This fell into disuse as gauge 1 at 1.75 inch was very close.
1:48 1⁄4" scale used for Queensland sugar cane railways[17] and US subjects[18] of 3 ft 6 in. (1,067 mm) ^ O21 – [1] 3 ft (914 mm) ^ O16.5 – UK 7 mm scale with 00 16.5 mm gauge, used to model gauges between 2 ft (610 mm) and 2 ft 6 in (762 mm). ^ O14 – Finescale modelling of British 2ft gauge using 7 mm O scale and a unique 14 mm gauge.
Various scales may be used for different drawings in a set. For example, a floor plan may be drawn at 1:50 (1:48 or 1 ⁄ 4 ″ = 1′ 0″) whereas a detailed view may be drawn at 1:25 (1:24 or 1 ⁄ 2 ″ = 1′ 0″). Site plans are often drawn at 1:200 or 1:100. Scale is a nuanced subject in the use of engineering drawings.
